Hassle-Free Exchanges & Returns for 30 Days. · 6-Month Limited Warranty. · Shipped from a global seller. Price includes all duties. 1 Use 5 indicators to indicate: normal, phase loss (voltage three-phase unbalance), reverse phase, overvoltage and undervoltage. 2 The base of the protector adopts a rail type with two screw holes, which can be directly installed separately or mounted on the HT35 rail. 3 Phase loss protection means that when the protected line is in the running state or non-operating state, any phase failure occurs, and the delay is 2S. 4 Reverse phase protection, a protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action. 5 Overvoltage protection means that the voltage of the protected line is higher than the set value, and the delay is 3~8S, and the recovery is 6~20VAC.
